The graph shows that the range of the function is 0.9 ≤ M ≤ ∞.

A linear function can be represented by a line. The standard form for this equation is: y=mx+b , for example, y=5x+8.

All functions present their domain and range. The domain of a function is the set of input values for which the function is real and defined. In the other words, when you define the domain, you are indicating for which values x the function is real and defined. While the domain is related to the values ​​of x, the range is related to the possible values ​​of y that the function can have.

From the graph it is possible to see that: the function is a linear function, the values of the coordinate x are represented by the volume (liters) while the values of the coordinate y are represented by the mass (kg).

The question asks for the range of the function. Therefore, you should indicate the possible values ​​of y that the function can have.

For this, you should analyze the axis-y. See that for x=0, the graph shows y =0.9. Therefore, the function starts for values of y >= 0.9 kg. It is possible to verify that when the volume increases, the mass also increases. With this information, you can find that the range is 0.9 ≤ M ≤ ∞.

1) The first thing to do is to find the vertex. So let's do it, considering that we already have the vertex and then we can find the coefficients. Note that all functions have a=1:

2) Now, let's find the other coefficient "c", since we've got a,b.

3) Thus the answer is:

Step-by-step explanation:

so, I understand, the given series is written in binary form.

a1 = 1 = 1×2⁰ = 1

a2 = 11 = 1×2¹ + 1× 2⁰ = 3

a3 = 111 = 1×2² + 1×2¹ + 1×2⁰ = 7

a4 = 1111 = 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 15

a5 = 11111 = 1×2⁴ + 1×2³ + 1×2² + 1×2¹ + 1×2⁰ = 31

...

we see, that

an = 2×(an-1) + 1

a1 = 1

a2 = 2×a1 + 1

a3 = 2×a2 + 1 = 2×(2×a1 + 1) + 1 = 4×a1 + 2 + 1

a4 = 2×a3 + 1 = 2×(2×a2 + 1) = 2×(2×(2×a1 + 1) + 1) + 1 =

= 8×a1 + 2×2 + 2 + 1 = 8×a1 + 7

...

an = (2^(n-1))×a1 + an-1

because

an = 2×(an-1) + 1,

an-1 = (2^(n-1))×a1 - 1

therefore,

an = 2×(2^(n-1))×a1 - 1 = (2^n)×a1 - 1

the sequence of the sums of the first n elements

s1 = a1 = 1

s2 = a1 + a2 = 1 + 3 = 4

s3 = a1 + a2 + a3 = 7 + 3 + 1 = 11

s4 = a1 + a2 + a3 + a4 = 15 + 7 + 3 + 1 = 26

...

(i)

it is NOT a geometric sequence.

for a geometric sequence

an/an-1 = r, and r must be a constant ratio for any n.

but

7/3 = 2.333333...

15/7 = 2.142857143...

these are different, so, the sequence itself is not geometric.

neither is the sequence of the sums of the series. because

11/4 = 2.75

26/11 = 2.363636363...

are different.

1, 2, 4, 8, 16, 32, ... is a geometric sequence (constant r = 2).

but not

1, 3, 7, 15, 31, ...

(ii)

11 111 111 111 111 111 111 in base 2.

the utmost right position is the 2⁰ position. every position further to the left multiples the position value by 2. it is the same process as for numbers in base 10 (just there every position value is multiplied by 10).

we have 6×3 + 2×1 positions = 20 positions.

so, the position values go from 2⁰ to 2¹⁹.

as per the formula for "an" up there, we get

a20 = (2²⁰)×a1 - 1 = 1,048,576 - 1 = 1,048,575

Answer:

The triangle has sides of 36 feet, 72 feet, and 49 feet.

=====================================================

x = shortest side

2x = second side

x+13 = third side

The three sides add up to the perimeter of 157

(x)+(2x)+(x+13) = 157

4x+13 = 157

4x = 157-13

4x = 144

x = 144/4

x = 36

The shortest side is 36 feet.

The second side is 2x = 2*36 = 72 feet.

A function's inverse function reverses the action of a function, or f.

a) From the given table, we can use the coordinate points (-5, 1) and (0, 2)

The standard linear equation is y = mx + b

m = 2-1/0-(-5)

m = 1/5

Since the y-intercept is (0, 2), hence the required function is y = 1/5 x + 2.

y = 1/5x + 2

x = 1/5 y + 2

1/5 y = x - 2

y = 5(x-2)

The expression for the volume of the box is:

Mathematically, there is no restriction for the values of x, but phisically we know that x is a length and has a positive value, so x>0.

Also, we know that x can not be largest than half of the width, that is the smallest dimension of the piece of paper.

As the width is 11, we then know that x is smaller than 11/2=5.5.

In conclusion, the domain for x is:

The solutions are x=2 and x=7 approximately.

Because of our domain definition, we know that x=7 is not a valid solution, so the value of x that maximizes the volume is x=2.

The volume for x=0 is 0. Then, it will increase its value until x=2, where it reaches the maximum volume. From x=2 to x=5.5, the volume decrease until reaching v=0 at x=6.5.

Answer:

Domain: 0

Value of x that maximizes the volume: x=2.

From x=0 to x=2 the volume of the box increases.

The value of the length AB xcm = -3½ which is derived using the completing the square method, and satisfies the expression 2x² - 5x - 42 = 0.

To solve for the unknown value of a quadratic equation; say ax² + bx + c = 0:

From the derived quadratic equation, applying the method of completing the square as follows;

2x² - 5x - 42 = 0

divide through by 2

x² - (5/2)x - 21 = 0

add 21 to both sides

x² - (5/2)x = 21

divide the coefficient of x, square the result and add it to both sides

x² - (5/2)x + (5/4)(5/4) = 21 + (5/4)(5/4)

factor the left hand side of the equation

(x - 5/4)² = 21 + (25/16)

simplify the right hand side

(x - 5/4)² = 361/16

take the square root of both sides

x - 5/4 = (+ or -)(19/4)

then;

x = 5/4 + 19/4 or 5/4 - 19/4

x = 3 or x = -3½

The quadratic equation 2x² - 5x - 42 = 0 is true for the value of x = -3½.

The core concept of mathematics' calculus is functions. The unique varieties of relations are the functions. In mathematics, a function is represented as a rule that produces a distinct result for each input x. In mathematics, a function is indicated by a mapping or transformation. Typically, these functions are identified by letters like f, g, and h. The collection of all the values that the function may input while it is defined is known as the domain. The whole set of values that the function's output can produce is referred to as the range. The set of values that might be a function's outputs is known as the co-domain.

Given:

f(x)=√x, g(x)=x+9

The value of k is 9 for the function g.

To solve this problem we should have a brief concept of algebraic functions.

To solve this problem we have to follow a few steps.

Here f is a function of x and the relation with the function denotes as x²-2x. Also, g is a function of x and the relation with the function denotes as x− 2.

If we put, x = 2 on  f(x) = x²-2x. We can write, f(2) = 2²-2.2 = 4 - 4 = 0.

If we put, x = 2 on g (x) = x − 2. We can write, g(2) = x− 2= 2- 2 = 0.

Hence, we can conclude that f(2) = g(2) = 0.      ( proved)

Here, g(k) = 7. So, x = k in this relation.

We have to put x= k on g(x) = x− 2 ; now we can write, g (k) = k− 2.

g (k) = k− 2 = 7 as per the question. Therefore k = 7 + 2 = 9

We are to determine the equation of line by interpreting tabulated results between an independent variable ( x ) and a dependent variable ( y ).

A function is usually expressed as follows:

The above notation gives us the output ( y ) which is a function of input variable ( x ). This means that whatever relationship these two variables have the value of output ( y ) is related to the imput variable ( x ).

We are given a table/list of values of output ( y ) corresponding to each value of input variable ( x ) as follows:

Input ( x ) Output ( y )

3 -5

6 -4

9 -3

There are a series of steps that we must take to arrive at the equation that relates two variables.

Step 1: Determine the type of relationship between two variables by intuition

The first step in the process is the hardest of all. We have to critically analyze each input value ( x ) and its corresponding output value ( y ) with successive pair of values.

There are many types of relationships possible ( polynomial order, exponential, logarithmic, trigonometric, radical, etc .. ).

We can conjure up a way by comparing outputs of successive values to determine the type of relationship possible.

So looking at the first value:

The successive value:

The next successive value:

Here if scrutinize between each successive value of input variable ( x ) we see that there is a "3 unit step-up" in each pair of values i.e ( 3 -> 6 -> 9 ).

Next we compare each output values ( y ) for successive pairs. We see that with every step increase of 3 units in ( x ) value there is an increase of ( 1 ) unit in output value i.e ( -5 -> -4 -> -3 ).

Conclusion: Combing the result of above analysis we see that with each 3 step increase in input value ( x ) there is an increase in output value ( y ) by 1 unit.

This gives us the idea that the two variables are linearly related to one another.

Therefore, the type of relationship is:

Step 2: Recall the equation for the type of relationship between two vairbales x and y

Once we have determined the type of relationship between two variables. We will have to resort to our equation bank and pluck out the corresponding equation that expresses a LINEAR relationship i.e equation of a straight line.

The slope-intercept form of a straight line is:

Step 3: Determine the complete equation of function by defining the arbitrary constants.

The above equation is valid for all straight lines that express a linear relationship. However, we seek to find a unique straight line for the given set of points.

Every unique straight line equation would have either of the constants different. The constants defined in a striaght line equation are:

To determine these constants we will use the given pairs of coordinates of input and output variables, x and y respectively.

To determine the slope (m) of an equation:

The above expression relates the change in output value ( y ) with respect to change in input variable ( x ).

To determine the constant ( m ) we will use the conclusion from Step 1:

"3 step increase in input of ( x ) value there is an increase in output value ( y ) by 1 unit."

Therefore,

To determine the value of y-intercept ( c ). We will plug in the value of ( m ) into the general equation of a straight line written in step 2:

Now, we will use any pair of input and output value.

Substitute the pair of values into the derived equation expressed above and solve for constant ( c ):

Note: The above step implies that following equation must satisfy each and every data pair of point given to us ( table ). Or each and every value must lie on the line. For that each value must satisfy the equation of line.

Step 4: Write the complete equation of the relationship

Once we have evaluated the values of equation defining constants ( m and c ). We can simply plug in the values into the general equation relationship ( Linear - slope intercept form ) as follows:

Therefore, the equation for the set of values given to us is:
